verified Jun 17, 2026

ast-monkey-traverse is a utility library designed for traversing Abstract Syntax Trees (ASTs) and general JavaScript object/array structures recursively. The current stable version is 4.1.3. As part of the Codsen monorepo, it receives regular updates and maintenance. Its core functionality offers a simple API, `traverse`, which allows users to visit each node in a data structure, providing access to the current key, value, and an internal object containing contextual information like the current path in object-path notation. A key differentiator is its clear distinction in the callback for object keys/values versus array indices, and its explicit focus on pure ESM since version 3.0.0, which streamlined its module architecture. It also provides built-in TypeScript types, enhancing developer experience for type-safe applications.
